After the review of basic concepts of the meteorology and air quality modelling we analyse the hydro-thermodynamic equation system of atmosphere and air pollution transport equation. We’ll study the structure of atmospheric turbulence, concern with various order closure hypotheses. We’ll review the classification of the dispersion models (statistic and dynamic, Lagrange and Euler types, etc.). Construction of local and mesoscale air pollution and PBL models are also investigated. Air pollution model applications in Hungary especially in the Hungarian Meteorological Service will be investigated in the end of the course.

There are natural and man-made sources of ionizing radiation in the human environment. These affect populations groups in different manner depending on life style, conditions at work and other factors. During the study of environmental sciences, exposure of people to ionizing radiation may represent an individual agent on one hand, and also a factor of combined environmental effects, on the other hand.
Types of radiation, basic dosimetry terminology, sources and levels of environmental radiation exposure to human, deterministic and stochastic biological effects and health consequences of exposure to ionizing radiation, as well as basic principles of radiation protection and radiohygiene will be presented during the course. Environmental and health consequences of most severe

The international conventions were elaborated on those environmental problems which had been identified by the research community by means of environmental observations, analytic methods and models, and which could only be solved by the commitments of all those countries that were responsible for those problems and/or suffered from their adverse impacts. The subjects of the multilateral environmental agreements (MEAs) cover almost all components of the global environment and their large-scale processes. The lectures of this course demonstrate the essence of the most important agreements on environmental elements (atmosphere, transboundary water bodies, biosphere etc.), on human activities influencing the environment and their impacts (through the emission of pollutants,
